Claims

[Scope of utility model registration request]

A bracket 1 that supports the left and right ends of a muscle strength training device such as a barbell, a pair of left and right inner tubes 2 and 3 with the bracket 1 installed at the upper end, and these inner tubes 2 and 3 can be moved up and down, respectively. A pair of left and right column-shaped outer tubes 4, 5 are fitted into the inner tubes 2, 3, and locked rod receiving holes 6...6 are formed at a predetermined interval in the axial direction of the inner tubes 2, 3. At the same time, the outer tubes 4 and 5 have a circumferential surface at the upper end thereof, which is movable in the radial direction.
A locking device 7 is provided in which the distal end 7b of the locking rod 7a fits into the locking rod receiving hole 6, and by fitting the distal end 7b of the locking rod 7a into the locking rod receiving hole 6, the inner tubes 2 and 3 can be connected to the outer tube. 4, 5, in which the locking rod receiving hole 6 is fixed.
...6 is a horizontal wall surface 6a that engages with the upper surface of the tip 7b of the lock rod 7a, and the horizontal wall surface 6.
It is formed in a sawtooth shape by alternately connecting sloped wall surfaces 6b that are continuous at the upper end and gradually expand downward as they go downward.
The lock rod 7a is biased in the axial direction of the inner tubes 2 and 3 by a spring 7f so that the tip end 7b of the lock rod always fits into the lock rod receiving hole 6.
